Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

OBJECTIVE To evaluate the quality of Lufu Pill （LFP）.METHODS The high-performance liquid chromatography （HPLC） fingerprint of LFP was established using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 Edition）， and similarity evaluation was performed. Hierarchical cluster analysis （HCA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were performed using SIMCA 14.1 software. The contents of strychnine， brucine， liquiritin， notoginsenoside R 1 ， ginsenoside Rg 1 ， ginsenoside Rb 1 ， licoricesaponin G 2 ， and ginsenoside Rd in 12 batches of samples were determined by the HPLC method.RESULTS A total of 26 common peaks were identified in the HPLC fingerprint of 12 batches of LFP samples， and eight common peaks were identified as strychnine （peak 3）， brucine （peak 4）， liquiritin （peak 6）， notoginsenoside R 1 （peak 7）， ginsenoside Rg 1 （peak 8）， ginsenoside Rb 1 （peak 15）， licoricesaponin G 2 （peak 17）， and ginsenoside Rd （peak 18）. The similarities of 12 batches of LFP samples were all greater than 0.90. The results of HCA and PCA both showed that the 12 batches of samples were divided into two categories： S2， S4-S6， and S12 were grouped into one category， while S1， S3， S7-S11 were grouped into another category. The upper control limits for Hotelling’s T 2 and DMod X were 16.631 and 1.578， respectively. The variable importance in projection values of ginsenoside Rg 1 （peak 8）， ginsenoside Rb 1 （peak 15）， peak 20， strychnine （peak 3）， peak 11， notoginsenoside R 1 （peak 7）， peak 2， peak 17， peak 13， peak 10， ginsenoside Rd （peak 18）， peak 23， peak 26， peak 21， and peak 24 were greater than 1.The content determination results showed that strychnine， brucine， liquiritin， notoginsenoside R 1 ， ginsenoside Rg 1 ， ginsenoside Rb 1 ， licoricesaponin G 2 ， and ginsenoside Rd were 0.005%-0.018%， 0.005%-0.010%， 0.050%-0.118%， 0.033%-0.073%， 0.132%-0.248%， 0.122%-0.242%， 0.021%-0.043%， and 0.016%-0.048%， respectively.CONCLUSIONS The established HPLC fingerprint and content determination method are accurate and reproducible， and can be used for the quality evaluation of LFP. Ginsenoside Rg 1 ， ginsenoside Rb 1 ， strychnine， notoginsenoside R 1 ， and ginsenoside Rd may be the differential components affecting its overall quality.

Breast cancer is one of the most common malignant tumors among women worldwide, with an increasing incidence rate year by year, making it a significant public health concern. With the continuous advancement of tumor biology research, N 6-methyladenosine (m 6A) modification, as an important form of RNA modification, has attracted growing attention. The m 6A modification, the most prevalent RNA modification in eukaryotes, occurs in almost all types of RNA and plays a critical role in the occurrence, progression, and metastasis of breast cancer. It influences cell proliferation, apoptosis, and alterations in the tumor microenvironment, though the specific mechanisms underlying these effects require further in-depth investigation. Moreover, the specific patterns of m 6A modification demonstrate its potential as a novel biomarker for breast cancer, which could provide new directions for early diagnosis and prognosis evaluation.

Objective Inflammation and fibrosis are key features of diabetic nephropathy(DN).Triptolide(TP)exhibits anti-inflammatory and anti-fibrotic properties,though its mechanisms of action in DN remain unclear.CREKA(Cys-Arg-Glu-Lys-Ala)is a pentapeptide that specifically binds to fibronectin(FN),and the CREKA-modified liposome(CREKA-Lip)represents a novel FN-targeted drug delivery system.This study aimed to investigate the role of TP in diabetic db/db mice and determine whether encapsulation within CREKA-Lip enhances therapeutic efficacy while reducing the multi-organ toxicity of TP.Methods Eight-week-old diabetic db/db mice received tail vein injections twice weekly with vehicle,free TP,or CREKA-Lip/TP for 10 weeks.Urine and serum parameters were measured,and kidney,heart,liver,and testis tissues were collected for pathological evaluation.Protein-protein interaction networks were constructed using Cytoscape and its plug-ins to identify core targets and elucidate the therapeutic mechanism of TP against DN.Inflammatory,fibrotic,apoptotic,and lipid metabolism markers were evaluated in the kidneys of diabetic mice with DN and in high glucose-treated mouse mesangial cells and podocytes using qPCR,Western blot,immunohistochemistry,and immunofluorescence assays.Results TP administration reduced fasting blood glucose levels and glomerular mesangial expansion in diabetic mice.TP significantly suppressed renal inflammation,fibrosis,and apoptosis while enhancing lipid metabolism.Integration of network pharmacology,molecular docking,and transcriptomics revealed that TP ameliorated DN by inhibiting the JAK2-STAT1 signaling pathway.In vitro,TP inhibited high glucose-induced phosphorylation of JAK2 and STAT1,reduced collagen production in mesangial cells,decreased apoptosis,and improved lipid metabolism in podocytes.Moreover,CREKA-Lip/TP exhibited superior efficacy compared with free TP,with a more sustained reduction in urine albumin-to-creatinine ratio and greater inhibition of mesangial expansion.Notably,CREKA-Lip/TP treatment did not induce systemic toxicity.Conclusion TP improves renal inflammation,fibrosis,apoptosis,and lipid homeostasis,thereby ameliorating DN by inhibiting JAK2-STAT1 activation.Targeted delivery of TP via FN-binding CREKA-Lip enhances therapeutic efficacy while minimizing multi-organ toxicity.

OBJECTIVE: To assess the association between the single nucleotide polymorphisms (SNP) rs174575 and rs2845574 of the fatty acid desaturase 2 (FADS2) gene and gestational diabetes mellitus (GDM). METHODS: A total of 1 514 pregnant women who visited West China Second University Hospital of Sichuan University between January 1, 2013 and December 31, 2021 were enrolled in this study. Among them, 583 were diagnosed with gestational diabetes mellitus (GDM group), and 931 had normal pregnancies (control group). The SNPs rs174575 and rs2845574 of the FADS2 gene were analyzed using Sanger DNA sequencing. Plasma levels of insulin (INS), apolipoprotein A1 (apoA1) and apolipoprotein B (apoB) were measured using enzymatic methods, chemiluminescence and immunoturbidimetry. This study was approved by the Medical Ethics Committee of the West China Second University Hospital of Sichuan University (Ethics No.: 2020-036). RESULTS: The main genotype at the rs174575 C/G and rs2845574 C/T loci were CC in both GDM and control groups. No significant difference was found between the GDM and control groups regarding the genotypic or allelic frequencies of rs174575 and rs2845574 sites (P > 0.05). Among the GDM group, individuals with the GG genotype at the rs174575 site had lower plasma HDL-C levels compared to those with the CC genotype (P < 0.05), and had higher atherogenic indices (AI) compared with the CC and CG genotype (P < 0.05; P < 0.05). Individuals with the TT genotype at the rs2845574 site had higher AI compared with the CT genotype (P < 0.05). Among the control group, individuals with the GG genotype had lower diastolic blood pressure (DBP) compared to those with the CC genotype (P < 0.05). Additional subgroup analysis demonstrated that the rs174575 polymorphism was associated with AI levels in obesity subgroup of GDM, TG levels in non-obese subgroup of control and DBP levels in the obese subgroup of control (P < 0.05; P < 0.05; P < 0.05). CONCLUSION The FADS2 rs174575 and rs2845574 polymorphisms in GDM patients are associated wit HDL-C and AI levels, and the FADS2 rs174575 polymorphisms was also associated with DBP levels in normal pregnant women. The AI and DBP levels have a BMI-dependent effect.

Background and Aims:Coactivator-associated arginine methyltransferase 1(CARM1)is involved in the regulation of RNA and protein processing.Recent studies have revealed its crucial role in tumorigenesis and cancer progression.However,the correlation between CARM1 expression,pan-cancer prognosis,and the immune microenvironment remains unclear.This study was conducted to investigate the relationship between CARM1 expression and pan-cancer prognosis,immune microenvironment,and its potential biological mechanisms using bioinformatics approaches.Methods:Using the TCGA,GTEx,and HPA databases,the expression pattern of CARM1 in various cancers and its prognostic relevance were analyzed.The correlation between CARM1 expression and the tumor microenvironment,as well as immune checkpoint genes,were analyzed using TCGA data.The PPI network of CARM1-interacting genes was constructed using the STRING database.GSEA was performed to investigate the potential biological mechanisms of CARM1 in pan-cancer.Results:Compared to normal tissues,CARM1 was upregulated in most tumor tissues,and its expression was associated with prognosis in multiple cancers.CARM1 expression was correlated with immune cell infiltration and immune checkpoint gene expression.Enrichment analysis suggested that CARM1 might alter the biological function of urinary system tumors by affecting ribosome biogenesis.Additionally,it may influence the biological functions of digestive system tumors by modulating arginine biosynthesis,DNA replication,and the cell cycle.Conclusion:CARM1 is aberrantly expressed in tumor tissues and may serve as a prognostic biomarker for multiple cancers.It is associated with the tumor microenvironment and immune checkpoint gene expression in pan-cancer and may contribute to tumorigenesis through multiple biological pathways,making it a potential therapeutic target for pan-cancer treatment.

Objective:To investigate the effects of CO2 intracavitary laser combined with pelvic floor magnetic stimulation on surface electromyography(sEMG)values and pelvic floor three-dimensional ultrasound parameters in female patients with stress urinary incontinence(SUI).Methods:A prospective study was conducted on 92 female SUI patients treated at the outpatient department of Meizhou People's Hospital from October 2021 to July 2023.The patients were randomly divided into an observation group and a control group(n=46 each)using a random number table.Both groups received home-based pelvic floor muscle training.The control group additionally received pelvic floor magnetic stimulation,while the observation group was treated with CO2 intracavitary laser combined with pelvic floor magnetic stimulation.The urinary leakage status,treatment efficacy,pelvic floor muscle sEMG,pelvic floor three-dimensional ultrasound parameters,quality of life,and sexual quality of life were compared between the two groups.Assessments included the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF),the Incontinence Impact Questionnaire-Short Form(IIQ-7),and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire(PISQ-12).Results:1-hour leakage volume:0 g(observation group)vs.3 g(control group),24-hour leakage episodes:0 times(observation group)vs.0 times(control group),the observed differences were statistically significant(Z=-2.866,-2.355,P<0.05).Total effective rate:95.65%(observation)vs.58.70%(control),the observed differences were statistically significant(x2=4.083,P<0.05).Pelvic floor muscle sEMG(after treatment):Maximal fast contraction:(40.78±3.28)μV(observation)vs.(35.17±5.10)μV(control),Mean tonic contraction:(31.56±4.20)μV(observation)vs.(25.87±3.82)μV(control),Mean endurance contraction:(29.34±2.58)μV(observation)vs.(25.37±2.67)μV(control),all differences between the two groups were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).After treatment,both groups showed reductions in bladder neck descent(BND)during Valsalva maneuver,bladder-symphysis distance(BSD),urethral rotation angle(URA),and posterior vesicourethral angle(RVA).However,the observation group demonstrated significantly greater reductions compared to the control group(post-treatment data:observation group(24.30±3.21)mm,(2.34±0.23)mm,(56.40±5.87)°,(89.54±9.21)°;control group(26.21±3.48)mm,(3.57±0.35)mm,(60.29±6.45)°,(126.71±13.50)°.These differences were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).Similarly,both groups exhibited decreased scores on the ICIQ-SF and IIQ-7 scales,along with increased scores on the PISQ-12.Again,the observation group showed superior improvement,with statistically significant differences(t=11.478,13.168,6.631,P<0.05).Conclusion:On the basis of pelvic floor muscle training,CO2 intracavitary laser therapy combined with pelvic floor magnetic stimulation can effectively alleviate urinary incontinence symptoms in patients with female stress urinary incontinence(FSUI),enhance therapeutic efficacy,improve pelvic floor muscle strength and the stability of pelvic support structures,and promote quality of life and sexual function.
